  3. Reproduce steps:

  I'm working through the early stages of learning OpenStack via this
  framework: http://docs.openstack.org/developer/devstack/guides/single-
  machine.html

  * I installed CentOS7 minimal
  * I patched it via "yum update"
  * It has a static IP
  * I've set up a small /29 for floating IPs on the same subnet, no DNS/DHCP for them
  * I've created the "stack" user and granted sudo
  * using the "stack" user I installed devstack via "git clone https://git.openstack.org/openstack-dev/devstack";, followed by a local.conf change, and "./stack.sh"

  Expected result:
  * exercises would complete with success

  Actual result:
  * fail with this as the last 100 lines of output of the boot_from_volume.sh script:
